Bright ambient light can wash out a virtual image in a conventional augmented reality device. Fortunately, this problem can be prevented with a variable electro-active beam splitter whose reflect/transmit ratio can be varied or switched on and off rapidly at a duty cycle based on the ambient level. As the ambient light gets brighter, the beam splitter's transmit/reflect ratio can be shifted so that the beam splitter reflects more light from the display and transmits less ambient light to the user's eye. The beam splitter can also be switched between a highly reflective state and a highly transmissive state at a duty cycle selected so that the eye spends more time integrating reflected display light than integrating transmitted ambient light. The splitting ratio and/or duty cycle can be adjusted as the ambient light level changes to provide the optimum experience for the user.

Simple and cost-effective measurement of polarization components or the complete PSoL (the so-called Stokes parameters) is achieved without any mechanical movements or deformation by using liquid crystal elements. A transmission of a first polarization of light is greater than a transmission of a second orthogonal polarization of light and transmission of the second polarization is greater than 5%. In another of the different states, the device has different levels of transmission of the first and second polarizations of light. At least two orthogonal polarization component values characterizing the light can be resolved by comparing an intensity of light captured in a plurality of the different states.

A display panel producing system for producing a display panel including a substrate on which films are laminated includes a measuring device, an ink-jet coating device, and a control device. The measuring device is configured to measure an uneven shape of a front face of the substrate in production. The ink-jet coating device is configured to apply a film formation material with an ink-jet technology to form the films on the substrate. The control device is configured to control the measuring device and the ink-jet coating device. The control device controls the measuring device to measure the uneven shape for formation of the films by the ink-jet coating device and to determine a control target for the formation of the films by the ink-jet coating device appropriate for the substrate on which measurement of the uneven shape is performed based on a result of the measurement.

A method for spatial and intensity control of remote foci locations of an optical beam generated from a light source. First and second, axially-aligned, non-diffractive foci are created by passing the optical beam through a phase mask and a Fourier lens. The phase mask q(s) is designed to have an axial response according to the following equation: $E\left(u\right)={}_{-}^{+}q\left(s\right)\exp \left(-2u_{0}s\right)\exp \left(2\mathrm{us}\right)\mathrm{ds}.$
The properties of the phase mask may be altered to independently vary location and intensity of the first and second foci.
